Young lovers Angelo Buenavista and Yna Macaspac are at the heart of Pangako Sa’yo.
Angelo, the rebellious son of a powerful politician, falls in love with Yna, a simple but beautiful adopted daughter of a retired policeman. Unbeknowst to them, their love story is destined to repeat history.
20 years ago, Angelo’s father, Eduardo Buenavista, also fell in love with an innocent but headstrong barrio lass named Amor. But their relationship was doomed from the start. Eduardo’s mother, Dona Benita, despised Amor, as she was an impediment to her plan to marry her son to Claudia, the illegitimate daughter of Governor Zalameda. The arranged marriage would have saved their family business, and so Benita did everything to ensure that that happened. And so despite the lovers’ struggle to fight for their love, they eventually succumb to the pressures and machinations. Eduardo is made to believe that Amor betrayed him. And so when Amor tells him she is pregnant with his child, he refused to believe her. He sends her off and marries Claudia Zalameda. But for Amor, Eduardo’s greatest betrayal was the bombing of the mines in Talimpao. The tragedy killed her family and her child, Maria Amor.
Tested by fate and hardened by suffering, Amor vows to return and destroy the lives of those who caused her tragic loss. 20 years later, her day of reckoning comes. She crosses paths with Eduardo and Claudia, and their son, Angelo, whom Amor sees will play the biggest role in her revenge. Ironically, crossing Angelo means crossing Yna, his inamorata. Unbeknownst to Amor, crossing Yna Macaspac will lead her to the greatest tragedy of her life --- greater than what has befallen her in the past.
